Okay. So i think i wanna get into amp building. I was thinking a champ build, since it's a simple amp and I REALLY like the tone of my friend's silverface champ. I have fairly limited experience. I have soldered new pots into a circuit board in an amp, replaced a bias pot, obviously i can solder, bias, and drain caps. I can somewhat grasp a schematic. What's a good source for parts, and preferably a step-by step kinda beginner's guide?
